new and useful Improvements in RearlVheel Attachments for Flows; and I do hereby declare the, following to be full, clear, and exact description. of the invention,v

such as will enable others skilled. in the art to. which it. appertains to make and use the.

same. I 4 p This inventlon relates to improvements in rear wheelv attachments for plows and more particularly to: such as areadaptable for use on sulky plows, whereby a twowheeled plow maybe-convertedinto a three? wheeled plow,-one object ofthe inventionbeing to-construct and. apply the attachmentin such manner that thendetachable wheel.

will be caused to take side thrust which:

would otherwise come against. the landside of a plow, and at the same t me reduce frlction; at the bottom side ofthelandside.

A further object is to provide simple means for effecting vertical adjustment, of

the wheel, whereby the latter may be so. po

sitioned below the landside as to effect. an increase or decrease in the suction adjustment of the plow body to meet any conditions of the soil, and at the same time crease the draft of the plow.

A further object is to-- construct the mountings for the wheel that the side pressure on the wheel will so protect the bearplow; Fig. 3 is a sectional View, and Fig.

4: is a detail View of the wheel; Figs. 5 and 6 are views showing the disk 14:; Fig. 7 is a view showing the hub 22 and journal 21; Fig. 8 is a separate view of the disk 23; Fig. 9 is a fragmentary view of the auxiliary standard, and Fig. 10 is a similar view of the upper end of the auxiliary standard.

1 represents a plow standard to which a moldboard. VVhen the -ment of the wheel as above described, is to plow'body 2 is secured in any preferred manner:

An auxiliary standard 3 is pivotally at tached at a point between its ends to the plow standard by means of a suitable bolt stand projects downwardly and rearwardly from saidplow standard. .The pivotal connection of theauxiliary standard with the plow standard may be conveniently located approximately in line with the top of the plow body- From such pivotal connection, the auxiliary standard projects upwardly parallel with theplow standard and at or near itsupper end is madeawith an elongated slot 5ffor the'passagle of a bolt 6, which latter also passes through a suitable hole in. the plow' standard; and serves to normally secure the upper end of the auxiliary standard rigidly to the plow standard. The auxiliary standard; is alsoprovided at or near its upper end with a lug 7 which to p projects over the rear edge of the plow I standard and is perforated for the passage of an adjusting screw 8, the inner end ofv which engages the rear edge of the plow standard andserves to turn the auxiliary standard'on its pivotal support 4 (when the bolt 6 shall have been loosened) and thus effect an adjustment of a rear wheel 9 mounted. atthe lower end of said auxiliary standard, such adjustment effecting a vertical. movement of said wheel for the purpose of'adjusting the suction of the plow body 2.

The lower portion of the auxiliary standard is connectedwithjthe mold-board of the plow body 2, by means of a brace 10, one endof which. may be screwed to said auxiliary standard and the otherend provided with. an arm 11 having an elongated slot 12 for the passage of a bolt 13 secured to the vertical adjustbeeflected, the connection-of the brace to the mold board may be loosened.

The mountings for the wheel 9 at the lower end of the auxiliary standard are such that said wheel will take the landside thrust and will also relieve the bottom of the landside of the plow of considerable friction.

In constructing the wheel mounting, I provide a disk 14; having annular ridges 15-16 the latter being disposed within an. annular rib 17 on one face of the wheel. The rib 15 of the disk enters a hole 18 in the center of the wheel, and the rim portion of the disk lies against an annular rib 19 on the wheel. The disk is rigidly secured to the wheel by means of bolts 20. A tubular journal 21 (preferably conical in form) projects outwardly from the disk 14 and passes through a hub 22. A disk 23 is disposed on the end of the hub 22 so as to cover the end of the tubular spindle and to prevent said disk from turning it is provided with a pin 24: to enter a notch 25 in the end of the spindle. A bolt 26 having a head at one end, passes through the disk 23, tubular spindle 21 and disk 14C, and is threaded at its outer end to receive a nut 27. The hub 22 is provided with perforated lugs for the accommodation of bolts 28, and the auxiliary standard is formed near its lower end with a hood 29 which receives and houses the outer end of the Wheel mounting. The bolts 28 pass through openings in the auxiliary standard at respective sides of the hood 29 and serve to secure the wheel mounting tosaid auxiliary standard.

The auxiliary standard is provided at its lower end with a toe 30, to which an arm 31 is secured,'one end ofsaid arm terminating in a scraper 32 for the inside of the wheel 9. The arm 31 projects upwardly from its connection with the auxiliary standard and at its upper end is bent laterally over the wheel, and'has a scraper 33 adjustably secured thereto, for the outer face of the wheel. A scraper 3st for the peripheral portion of the wheel is attached to the arm 31 at a point between the ends of the latter.

Slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope and hence I do not wish to restrict myself to the precise details herein set forth.

Having fully described my invention what F I claim as new and desire to secure by Letters-Patent, is 2-- l; The combination with a plow standard, of an auxiliary standard removably and pivotally attached between its ends thereto,

a rear wheel mounted near the lower end of said auxiliary standard, and means at the upper end of the auxiliary standard and cooperating with the plow standard for adjusting said auxiliary standard on its pivotal support to adjust said wheel.

7 2. The combination with a plow standard, of an auxiliary standard pivotally attached between its ends thereto and provided at its upper end with a lug projecting over the rear face of the plow standard, an adjusting screw passing through said lug and engaging the plow standard, and a wheel mounted near'the lower end of said auxiliary standard.

3. The combination with a plow standard, of an auxiliary standard'pivotally attached between its ends to the plow standard and projecting downwardly and rearwardly from the same, a rear wheel mounted near the lower end of said auxiliary standard, said auxiliary standard having an approximately horizontal slot above its pivotal attachment to the plow standard, a bolt passing through said slot and the plow standard, a lug projecting from the auxiliary standard over the rear face of the plow standard, and an adjusting screw passing through said lug and engaging the plow standard.

4. The combination with a plow stand ard and a plow body secured thereto, of an auxiliary standard pivotally attached between its ends to the plow standard, a wheel mounted near the lower end of the auxiliary standard and disposed behind the plow body, means adjustably securing theupper-end of the auxiliary standard to the plow standard, and a bracesecured at one end to the lower portion of the pivoted auxiliary standard and adjustably secured at itsother end to the plow body.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
